Interspecies Correlation Estimation

Species Sensitivity Distributions

Species sensitivity distributions (SSDs) are cumulative probability distributions of toxicity values for multiple species. For Ecological Risk Assessment, the chemical concentration that may be used as a hazard level can be derived from an SSD using a specified percentile of the distribution.

This SSD module generates a distribution for a chemical from Web-ICE estimated toxicity values and the entered toxicity of up to 25 surrogate species.
